STEAM-CONDENSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 250,203, dated November 29, 1881,

(No model.)

To all whom it may concern Be it known that 1, JOHN OHARLESWORTH,

a subject of Great Britain, residing atOhieago,

in the county of Cook and State of Illinois, in the United States of America, have invented a certain new and useful Improvement in Steam-Condensing Apparatus for Steam-Engines, of which the following is a specification.

My invention relates to improvements in steam condensing and economizing attachments for steam-engines in which turbine and propelling wheels inclosed in air-tight chambers and connected to the watertank and steam-exhaust of an engine operate together so as to condenseand savethe exhaust-steam, and at the same time heat the water in the tank, the water from the tank furnishing the operating power; and the objects of my invention are, first, to provide an arrangement of turbine andpropelling wheels, pipes, and water-tank in a steam-engine, whereby the water from the tank will operate the wheels, and by said operation to be returned to the tank; second, to save and condense the exhaust-steam from an engine by the water from the tank without allowing it to escape; and, third, to heat the water in the water-tank of a steamengine by means of the exhaust-steam. I attain these objects by the construction, arrangement, and combination of the mechanism illustrated in the accompanying drawings, in which- Figure l is a front-side view of my attachments. Fig. 2 is a top View of the same. Fig. 3 is aview of the propelling-wheel, showing its construction.

Similar letters refer to similar parts throughout the several views.

A represents a water-tank of a locomotive or other engine. It is made in the usual way, and placed in any suitable or conveuientplace near the boiler, and is air-tight.

[B is an iron pipe connecting tank A with air-chamber D, and is for the purpose of conveying the water from A to D.

O is a turbine wheel inolosed in the airtight chamber D, and revolves therein, the water from tankA through pipe B operating the same.

D is an air-tight chamber or box, made of .i-steam from N to A.

iron and attached to the engine in any convenient position below thelevel of the tank A, so that the water from A will flow into it.

E is a revolving shaft, to which 0 is rigidly attached and revolving therewith. At one end E has its bearing in F, and at the other it is rigidly attached to the center of cog-wheel G. E passes through D.

F is a bearing for E, and is secured to the engine in any convenient place.

Gr is a cog-wheel on the end of E, and operates in connection with cog-wheel H.

H is a cog-wheel rigidly attached to shaft I, revolving therewith, being operated by its connection with G.

1 is a revolving shaft passing through the center of the air-chamber N, propelling-wheel M, and cog-wheel H, and is supported by the frame K. At one end it is secured to H, and at the other turns in the bearing 0, which is on the side of the chamber N..

K L is an iron frame-workorsupport for the shaft I. It is secured in any suitable manner to bring the several parts into proper position. One end of L is secured to box or chamber D.

M is a propelling-wheel, made in the shape as shown in Fig. 3. It is inclosed in the airtight chamber N, and is secured in its center to the shaft I, and revolves therewith.

N is an air-tight chamber or box,suff1ciently large to allow M to revolve freely therein. It is placed near D, and in such a position as to allow the several parts to work.

1? is an iron pipe connecting chamber D with N, and is for the purpose of allowing the water and condensed steam to flow from D to N.

B is also an iron pipe. It connects chamber N with the water-tank A, and is for the pun pose of conveying. the water and condensed The pipe Bis connected to the tank near its top, as shown in the draw lugs.

S is a bearing and support for shaft I.

T is an iron pipe connecting the exhaust steam chambers or drum of the steam-engine with the air-chamber D, and is for the purpose of conveying the exhaust-steam into D without allowing it to escape into the air.

All of the several parts are arranged and connected in the manner as shown in Fig. 1,

and are secured to the engine in a manner to allow them to work freely.

The manner of operation is as follows: The several parts are attached to the engine, the pipe T to the steam-exhaust. The water from the tank A is allowed to flow into the pipe B, when it will pass into the air-tight chamber D, and will revolve the wheel 0 and shaft E, thereby turning the wheel G, which, in connection with wheel H, will turn the shaft I, thereby revolving the wheel M. The water in chamber D will be forced by wheel 0 through pipe 1? into chamber N, and from thence by M through pipe R back into the tank A. All the time the exhaust-steam from the engine passes through pipe T into chamber D, and coming into contact with the water is condensed and carried into the tank, and in so doing heating the water in the tank. A vacuum will be created in the chambers D and N and connecting-pipes P and 1t, thereby preventing resistance to the free movement of the water and condensed steam. Suitable regulating-valves may be attached to tank end of pipes B and B, so that the flow of water maybe shutoff, if desired.

The tank A has the usual connection with the boiler, so as to supply water. This arrangement effects a perpetual condensation of the exhaust-steam, and'allows none of it to es cape, and at the same time furnishes a supply of heated water in the tank, always ready for use for the boiler, instead of cold water, now

uniformly used, thereby preventing the danger of explosion of the boiler from sending cold water into a heated boiler. The steam thus heating the water in the tank purifies it of all sediment and animal matter, and thereby prevents incrustation in the boiler or boilers.

My device can be used as a perpetual water 40 H, whereby the wheel M is revolved and the water and condensed steam propelled, all arranged substantially as shown and described.

2. In a steam-condensing apparatus, the propelling-wheel M, in combination with the airchamber N, having tank-connecting pipe R, whereby the water and condensed steam are forced into the tank A, all arranged substantially as shown and described.

3. The combination, in a steam-condensing apparatus, of the tank A, pipe B, exhaust-pipe T, chamber D, turbine wheel 0, having shaft E, carrying cog-wheel Gr, connecting-pipes P It, chamber N, and propelling-wheel M, having shaft I, carrying cog-wheel H, the water from the tank furnishing the operative power, and all arranged substantially as shown and described.
